A fibrous, non-woven thermal insulation comprises synthetic polymeric resin microfibers, staple fibers and bonding fibers which are randomly oriented and randomly intermingled in a single layer. The microfibers comprise between 0% and 95% by weight virgin synthetic polymeric resin and between 5% and 100% by weight recycled polyethylene teraphthalate. In one embodiment the microfibers have an average diameter between 1 to 10 microns and comprise between 5% and 80% by weight of the insulation; the staple fibers have an average diameter between 10 and 30 microns and comprise between 5% and 90% by weight of the insulation; and the bonding fibers have an average diameter between 0. 9 and 15 denier and comprise between 5% and 95% by weight of the insulation. The bonding fibers have thermoplastic surfaces with a lower temperature softening point than the microfibers and staple fibers and bond the fibers together to form the insulation material.

A novel economical hardboard is provided which comprises (a) about 1-40 wt % of a porous additive having a particle size in the range of about 0. 1-2 mm; (b) about 65-97 wt % of cellulose fibers; (c) about 2-5 wt % binder; and (d) about 1-4 wt % wax. Also provided is an efficient economical process for the production of the above described inventive hardboard comprising the steps of formulating an aqueous mixture of the above ingredients, then dewatering the aqueous mixture, and finally heating the mixture at a temperature and time sufficient to cure the binder.

A composite filter media includes a fibrous filtration layer of randomly oriented fibers and one or more pleatable stiffening layers which enable the composite filter media to be pleated and hold or retain its pleats. The pleatable stiffening layer(s) may enhance the dirt holding capacity of the composite filter media especially when positioned upstream of the fibrous filtration layer. The composite filter media may also include a flexible covering layer which functions to block the loss of fibers from the fibrous filtration layer. Preferably, the mean fiber diameter of the fibers in fibrous filtration layer increases and the density of the fibrous filtration layer decreases throughout the thickness of the fibrous filtration layer from one major surface to the other major surface of the fibrous filtration layer.

An air filtration media comprises a single layer of randomly oriented and randomly intermingled synthetic, polymeric resin microfibers, staple fibers and bonding fibers. The microfibers, taken as a whole, have an average fiber diameter no greater than 5 microns and comprise between 50% and 90% by weight of the filtration media; the staple fibers, taken as a whole, have an average fiber diameter between 10 and 30 microns and comprise between 5% and 45% by weight of the filtration media; and the bonding fibers, taken as a whole, have an average fiber diameter between 10 and 30 microns and comprise between 5% and 25% by weight of the filtration media. The bonding fibers have thermoplastic surfaces with a lower temperature softening point than the microfibers and the staple fibers and bond the fibers together to form the air filtration media.

Apparatus for producing organic fibers by means of a centrifugal spinning process. The fiberizing disc and the molten material introduction nozzle are designed to prevent the molten material from escaping the disc prior to being fiberized. The heater for heating the material in the disc is designed to accommodate the lower melt temperature of the material to be fiberized. Also, means are provided for diverting the flow of fibers from the disc to cause the fibers to be more precisely or uniformly deposited. The fibers are substantially immediately cooled upon exiting the fiberizing disc, resulting in a fiber structure that is at least about 60% amorphous.
